Replace main furnace door and blower access panel.NOTE: If a bypass humidifier is used, setup switch SW1-3 (LowHEAT Rise Adjust) should be in ON position. This compensatesfor the increased temperature in return air resulting from bypass.NOTE: If modulating dampers are used, blower motor automati-cally compensates for modulating dampers.Step 3—Prime Condensate Trap With WaterCondensate trap must be PRIMED or proper draining may notoccur. The condensate trap has 2 internal chambers which canONLY be primed by pouring water into the inducer drain sideof condensate trap. Failure to follow this caution will result inintermittent unit operation or performance satisfaction.1. Remove upper inducer housing drain connection cap. (SeeFig. 52.)2. Connect field-supplied 1/2-in. ID tube to upper inducerhousing drain connection.3. Insert field-supplied funnel into tube.4. Pour 1 quart of water into funnel/tube.

Remove funnel and tube from inducer housing and replacedrain connection cap and clamp.Step 4—Purge Gas LinesIf not previously done, purge the lines after all connections havebeen made and check for leaks.A02349Fig. 50—A/C or CF Airflow Selection ChartBased on 350CFM/TonAIR CONDITIONING AIRFLOW 040,060 & 080-14MODEL080-20 & 100MODEL 120 MODELTONS (12,000 BTU/HR) (CFM)1-1/2 525 XX2 700 X X X2-1/2 875 X X X3 1050 X X X3-1/2 1225 X X X4 1400 X X5 1750 X6 2100 XX-INDICATES AN ALLOWABLE SELECTION.A/C OR CF AIRFLOW SELECTION CHARTBASED ON 350 CFM/TONMODELSIZE040, 060,080-14 DEF 5252 700 875 1050 1 1225 1225 1225080-20, 100 DEF 700 875 1050 1225 1400 17501 1750120 DEF 700 8752 1050 1225 1400 17501 21001.DEFAULT A/C AIRFLOW WHEN A/C SWITCHES ARE IN OFF POSITION2.DEFAULT CONT.
